Will a PAL dvd play in my computer? either NTSC or multi-region) but when we tried the computer, it worked ok. So back to the original question, will a PAL dvd play on my US computer's dvd player?
The issues of regions and NTSC/PAL/SECAM concern two different things in the audiovisual setup. The first refers to code restrictions (software) and the other to display modes that is more of a hardware issue. Most of the Go Video players sold in the US have a secret menu that allows one to change the player to play disks from all regions. Unfortunately, for an NTSC player to play a PAL video (or vice versa) one requires that the DVD player to have a chip capable of converting the PAL signal to NTSC in order to output it to a NTSC television. Rarely do televisions have that video conversion chip hence the focus on DVD players here.
Computers do not have that restriction - one can play whatever one likes. HOWEVER, keep in mind that modern computers have a restriction of the number of times one can change the region setting - 5 changes and it will be set to whatever region it was changed to last. There are a few solutions, flash the firmware of the DVD-drive so that it also becomes region-free, or find an application that shields the region code of the DVD if the disk and player are on different regions. I believe VLC in both Windows and Mac OS X have options to do so.
There are also more illegal options (thanks MPAA) but I won't delve into it.
